Mostly condor 8.2 (there are a few 8.4 nodes)

It is using partitionable slots, fairly straightforwardly:

Now I have seen allusions to issues between partitionable slots and 
preemption but not exactly what they are - I had an impression it was 
something to do with evicted jobs leaving the slots fragmented, rather 
than preemption just not happening.
